Another option is a hardware filter: yellow glasses. I am unsure if the 
following statement is trustworthy, but marketing is based on suppressed 
chromatic aberration inside eyes.

I think, you should decide what is better for your sight: active screen 
and perhaps dark theme or paper-like reflective display. Some people 
complains that particular devices may have annoying flickering at low 
screen brightness due to pulse width modulation. Some devices have too 
bright screen even when brightness is set to min value.

If it is acceptable to you to limit device usage to reading and 
handwritten notes then a e-Ink might be really great. You can extend 
such notes in Emacs on a PC later.

P.S. Concerning free PDF annotation tool, I have not tested if it is 
convenient and available on Android, but Firefox-106 release notes have 
the following entry:

adding signatures.

Almost certainly "edit" in their parlance in namely annotations, not 
real changes of PDF structure.
